ATTACHMENT FOR HAND-OPERATED BRUSHES.

Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed February 17, 1906. Serial No 301,625.

To all whom it may concern:

Be it known that l, J OSEPH GRAF, a citizen of the United States, and aresident of Paterson, in the county of Passaic and State of New Jersey,have invented a new and Improved Attachment for Hand-Operated Brushes,of which the following is a full, clear, and exact description.

My invention relates to hand-operated brushes and the like, my moreparticular object being to provide the brush or analogous member with ashield movable by hand for the purpose of preventing the substanceapplied by the brush from discoloring or injuring other surfacesimmediately adjacent to that being operated upon by the brush.

The invention relates more particularly to an attachment forhand-operated brushes of the kind used for spreading paint and varnish,the attachment being flexibly connected with the brush in such mannerthat the operator while using the brush may move the shield relativelyto the same within certain limits.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a fragmentary plan view of a brush equipped with myattachment and cocupying its normal position. Fig. 2 is a somewhatsimilar view showing the screen as movable relatively to the brush, soas to stretch the tensile spring connecting the two together and Fig. 3is a side elevation, partly in section, showing the screen occupying itsnormal position relatively to the brush.

The brush handle or stock is shown at 4 and the bristles at 5.Encircling the stock 4 is a spiral spring 6, this spring being of thesocalled tensile type. It is connected at 7 directly with the brushhandle or stock 4 and terminates at its other end in a head 8, whichengages the annular shield 9. This shield is provided wth a planeportion 10 and with a flange 11. The flange 11 is used by the operatorin moving or adjusting the shield 9. The arrangement of the parts issuch that when the operator grasps the handle 4 and presses one or moreof his fingers against the flange 11 the tensile spring 6 is stretched,as indicated in Fig. 2, so that the portion 10 moves into the positionindicated in Fig. 2. Then as the brush is used the bristles 5 may be somanipulated as to paint a surface which is close up to another surfacenot to be painted, the portion 10 protecting the surface last mentionedand avoiding the possibility of any paint getting thereupon. Forinstance, in painting the woodwork of windows it may be desirable toprevent the paint from being applied upon the glass panes, andespecially upon those portions thereof very close to the woodwork andwhere the removal of the paint without damage to the woodwork canoccasion more or less difficulty. In this case any superfluous painttending to get upon the glass is received by the inner face of theportion 107 The portion 10 is provided with a bead 10 for followingangles without causing undue wear upon the portion 10.

The operation of my device is as follows: the operator grasps the handle4 and manipug lates the brush after the manner of an ordinary paintbrush. Coming, however, to some portion of the work which is immediatelyadjacent to a wall or surface which it is desired to protect from theaction of the paint, the operator presses against the flange 11 andbrings the portion 10 into the position indicated in Fig. 2. It will benoted that the spring 6 by allowing more or less movement between thehandle 4 and the shield 9 allows the bristles 5 to move angularly withincer tain limits in order that the painting may properly be done and thatthis angular movement of the bristles 5 and of the handle 4 does notnecessarily cause the movement of the shield 9 for the moment.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination of a brush, a shield encircling thesame and provided with a portion for preventing the application of paintfrom said brush to a predetermined surface, and a flexible connectionfrom said brush to said shield.

2. The combination of a brush, a shield of sheet metal encircling thesame and having one of its edges bent up in the form of a bead forlodging against woodwork or the like, said name to this specification inthe presence of shield being;1 furtlliler pil'lovi'ied with a flange twosubscribing witnesses.
